Voclosporin: A Novel CNI
• Novel CNI developed as a structural change from cyclosporine A, incorporating a single carbon extension with a double-bond
• Voclosporin has a consistent dose response potentially eliminating the need for therapeutic drug monitoring
• 4x potency over cyclosporine A
Source: Aurinia. Data on file.
Potential disease-modifying podocyte stabilization, which protects against proteinuria

Aurinia Studies Evaluating Voclosporin in Active Lupus Nephritis
AURION(Proof of Concept)
• Single arm, twin center exploratory study
• Biomarkers at 8 weeks: 25% reduction in UPCR. C3/C4, anti-dsDNA normalization
• N = 7
• Primary analysis: # patients achieving biomarkers and # of these patients who go on to achieve Week 24 or Week 48 remission
Completed Trials
AURORA(Phase 3 RCT)
• Phase 3
• Double blind RCT
• N = 357
• Active control
• Primary endpoint: 52 week renal response
AURA-LV (Phase 2 RCT)
• Phase 2
• Double blind RCT
• N = 265
• Active control
• Primary endpoint: 24 week renal response
• Statistically significant result in active LN patients

AURORA Study Conclusions
• The positive benefit-risk profile observed in AURORA (n=357) confirms the treatment effect seen in AURA-LV (n=265) when comparing voclosporin 23.7 mg BID in combination with background standard of care versus standard of care alone.
• The odds of achieving Renal Response on voclosporin therapy were 2.65x greater than control, while maintaining a comparable safety profile.
• Hispanic ethnicity and Black race LN patients, often severe and difficult to treat subgroups, also noted improved Renal Response with voclosporin.
